U bazi podataka Flora Hrvatske (FCD) rod Colchicum dosad je bio zastupljen sa sedam svojti. Za dvije je bila dvojbena prisutnost u Hrvatskoj (C. arenarium Waldst. et Kit. i C. cupanii Guss.), a za dvije taksonomski status (C. kochii Parl. i C. visianii Parl.). Nakon provedene literaturne revizije predlaže se uklanjanje vrsta C. arenarium, C. cupanii i C. neapolitanum (Ten.) Ten. koje prema dosadašnjim saznanjima ne dolaze na teritoriju Hrvatske. Utvrđeno je da vrsta C. doerfleri Halácsy, dosad smatrana sinonimom vrste C. hungaricum Janka, dolazi u Hrvatskoj (Velebit), pa je treba uvrstiti kao samostalnu vrstu u popis hrvatske flore. Primjenom molekularnih metoda osporen je tretman svojti C. visianii i C. kochii kao samostalnih entiteta već su obje uključene u jednu šire shvaćenu vrstu C. haynaldii Heuffel koja je rasprostranjena na većem dijelu Balkana. Također je potvrđeno da vrsta C. bivonae Guss. dolazi u Hrvatskoj, ali je zastupljena samo na nekoliko lokaliteta u sjevernom dijelu jadranskog primorja. Prethodno objavljeni nalazi mrazovca u Dalmaciji pod imenima C. bivonae i C. neapolitanum su po svemu sudeći pogrešni jer pripadaju C. haynaldii agg. Literaturna revizija je pokazala da je rod Colchicum u flori Hrvatske zastupljen sa šest vrsta: C. autumnale L., C. bivonae Guss., C, doerfleri Halácsy, C. kochii Parl., C. visianii Parl. i C. hungaricum Janka.Until now, the genus Colchicum L. (Colchicaceae) has been represented by seven taxa in the Flora Croatica Database (FCD). For two species (C. arenarium Waldst. et Kit. and C. cupanii Guss.) the appearance in Croatia was doubtful and for two other (C. kochii Parl. and C. visianii Parl.) taxonomic status was questionable. In this paper a detailed review of this genus in Croatian flora was carried out. After the audit, it is proposed to exclude from the list the three taxa (C. arenarium, C. cupanii and C. neapolitanum (Ten.) Ten.), because they do not occur on Croatian territory according to current knowledge. It was found that C. doerfleri Halácsy, previously treated only as a synonym of C. hungaricum Janka, occurs in Croatia (Velebit). Therefore, it should be included in the list of Croatian flora as an independent species. By applying the molecular methods, it was found that there is no justification for treatment of C. visianii and C. kochii as independent taxa, but both of them are included in a widely understood species C. haynaldii Heuffel, distributed in most parts of the Balkans. Additionally, it was found that C. bivonae Guss. occurs in Croatia, and until now it is found only in a few localities in the northern part of the Adriatic coast. Former findings of colchicums from Dalmatia noted as C. bivonae and C. neapolitanum are found as misidentifications and both of them properly belong to C. haynaldii agg. Following the literature revision the genus Colchicum is represented by six taxa in Croatian flora: C. autumnale L., C. bivonae Guss., C. doerfleri Halácsy, C. kochii Parl., C. visianii Parl. i C. hungaricum Janka
